Three people from south Wales are arrested after police seize cannabis worth up to £139 million, described by multiple outlets as the UK’s biggest ever such seizure. The drugs are reported to have been shipped from Canada and discovered in the UK’s dock area, where officers intercept and recover the consignment. Authorities say the arrests follow investigation linked to the importation and the intended distribution of the cannabis once it reaches the country. Both sources state that the individuals arrested come from south Wales and that the quantity involved is extremely large, with an estimated street value of up to £139 million. The reports do not describe additional details such as the exact port of arrival, the precise shipment size, or whether any other suspects are being sought. The case is presented as a record-breaking find, prompting enforcement action and ongoing investigation into the supply chain behind the attempt to bring the drugs into the UK from abroad.
